I Had A Biopsy Done Tuesday And Went Back Today

I had a biopsy done Tuesday and went back today for results, said the area they checked was begin, but I had mircocilifaction and wanted to do another biopsy Tomorrow ( Friday ). I really feel scared because breast cancer runs in my family, mother had breast cancer, mother two sister died with breast cancer and my cousion. Do you think the microcalifation is anything to worry about? The dr said she had seen area's like that begin and areas cancerous. You can tell I am not a doctor with the medical words the spelling.
